Frankly, the model did not please at all. Very sorry for the waste of money. The model was purchased over a year ago. First of all, the brush broke - it just stopped spinning. As a result, all the debris is simply clogged into the free space in the brush. I have no tools to measure the suction power, but if you just put your hand on it, you can clearly feel that at the moment the power is tending to zero. The lever to open the dust box is incredibly tight, opening under force. Therefore, part of the garbage often spills out and ends up on the floor. The vacuum cleaner is not maneuverable, it is inconvenient to move it. The spinning ball in the Dyson DC24 design is very large in diameter, making it impossible to clean the surface under the bed or low table. Plus, the vacuum cleaner is very noisy.
